Help With Julius or Sphinx

Hi, does anyone know how to get Julius, or Sphinx, to automatically transcribe audio from a file that has already been recorded.

I’ve been trying to figure them out, and I’m having a hell of a time understanding the manuals and the answers in the forums, they’re all to technical for me. Has anyone ever used it, or software like it, and can help me? :a0

At this point I’d appreciate any help I can get. Thanks.
